Since you don't reload I would pass on is gun. Factory ammo can be difficult to find and selection is very limited. The 307 was chambered for only a few years in the 80's, if I remember correctly, and was never a popular round. The 307 is basically a rimmed 308 and gives similar performance.

If you're interested in a lever gun with a longer range and more power than a 30-30 I would look at either a Browning BLR or a used Savage 99. Both rifles are available in 308Win and can shoot spitzer bullets.
